Hey there, I spotted this thread earlier in the day but I was at work and did't get a chance to read it properly. I'm so sorry that you've been let down so much by HCPs in the past. I can't imagine how much more difficult that makes things. I'm really glad that you've managed to reach out to friends/family though.
I'm not surprised that you were at the end of your tether! It's such a hard job being a parent and the early months can be bloody difficult. I'm a single parent. My eldest was a very easy baby/toddler (I was a single parent then). When my youngest was born (I was married at this point), I thought that it would be as easy...what a fool I was to think that!! She had tongue tie (sorted out when she was 10 days old) which made BFing bloody painful. She couldn't be put down/laid flat as she'd cry/scream. She didn't sleep properly. She couldn't even sit in a bouncer chair or car seat (neither were upright enough) - she had to be held upright (so I had her in a wrap most of the time). Turns out she had reflux. GP put her on meds for it and it slowly got better. But my God, it was effing hard work and completely ground me down. The meds from the GP, a good baby wrap/sling, and sleep training saved my sanity, and got my DD onto a more even keel.
If you were my mate, I wouldn't hesitate in offering help. I'd be so happy that you trusted me enough to come to me for help, and I'd be pleased to do what I could to help. Years back, one of my friends was in a real pickle with things and reached out for help: so I headed over, cleaned/tidied her place top to bottom, managed to get her washing machine fixed, helped her catch up on laundry/ironing/paperwork/life admin, batch cooked a load of meals for her and her children (enough to fill her freezer)....and looked after her kids whilst she had a proper rest and some time to herself. Sounds like silly stuff, but for her it was like a reset button and it meant that the mental load was taken off her for a while.
I really hope that you and your little one have a lovely and peaceful first Christmas together and that you get the support and help you need. I wish I was closer. Wishing you all the best x
